Anyone know if these readings are any good, battery been fully charged around 2 weeks ago and ive driven car today after about 4 days of been parked up. 

 

Hello Mo,

’...fully charged about 2 weeks ago and driven ( how many miles?) today ...’ and some of the values not looking too healthy (64% charged and your opening voltage figure of below 12v), suggests the battery is below par. Do you know if this battery is the original? 

If it is, then it’s highly likely it’s on its last legs, and if so, if it were mine, then I would only replace it with a quality brand such as Varta/Bosch, bought on line at the most competitive price.

Having said all that, it would obviously be well worth getting the battery efficiency checked before replacing it, and getting the alternator output checked at the same time. 

So one step at a time and get the battery checked. If it is serviceable, and the alternator output is fine, then there is another possibility to consider, but no need to go into this yet.

Perhaps you could let us know how you get on.

Kind regards,

Gareth.
